The Colwell laboratory’s research has focused on understanding the mechanisms underlying circadian rhythms in mammals. Dysfunction in the timing of these daily cycles is a key symptom in a number of neurological and psychiatric disorders.
Better understanding of the basic biology of this timing system should result in new therapies to improve the quality of life of these patients and the people who care for them.
